Given:

The sound from a mosquito is produced when it vibrates its wings at an average rate of 500 vibrations per second. 

To do:

To find the time period of the vibration.

Solution:

Here given, the number of vibrations in a second $=500$

We know that number of vibrations in a second is called the frequency of the wave.

So, the frequency $f=500\ Hz$

So, time period $T=\frac{1}{f}$

Or $T=\frac{1}{500}$

Or $T=0.002\ second$

Therefore, the frequency of the sound produced by the mosquito is $500\ Hz$ and its time period is $0.002\ second$.
